Another very important object? ofwthe infi -ventioniresides intheprovision; of a gold. separator of this nature which is "compare-q tively simple iIr-its construction, strong and; durable, thoroughly reliablegin operation} and otherwise well adapted to the purpose} for which it'isdesigneds I v 7 With the above and numerous other objects in View as willa-ppear as the description proceeds, the invention resides in certain novel features of construction, and in the 'combination and arrangement of parts as will be hereinafter more fully described and claimed.

Referring to the drawings in detail, it
